Mikeius clavatus Pujade-Villar & Restrepo-Ortiz sp. n. Fig. 1E

Diagnosis.

Differs from all the other species of Mikeius in having the antenna strongly clavate with the six terminal segments 1.5 times wider than previous segments ( Fig. 1E ); further distinguished from Mikeius berryi and Mikeius grandawi by the absence of a mesopleural carina.

As in subfamily description (see above) with the following specific characters.

Length. Female 2.8 - 3 mm. Male unknown.

Coloration. Head and mesosoma black, antenna yellowish, except scape, brown, metasoma pale brown. Legs pale yellow, except coxae, brown.

Antenna. ( Fig. 1E ) Female. Strongly clavate, 11 flagellomeres, antennal formula: 8(4): 4(4): 5(3): 3(3): 3(3): 3(3.5): 4(5): 5(6): 5(6): 6(5): 5(6): 5(6): 7(4). Placoid sensillae from F7 to terminal segment.

Mesosoma. Mesoscutum slightly striate. Notauli complete of uniform width. Antero-admedian lines weak. Median mesoscutal line very short. Scutellar foveae round to subquadrate, not delimited posteriorly. Mesopleural furrow absent.

Forewing. Radial cell 2.4 times longer than wide.

Metasoma. Base of T3 with an almost complete hairy ring.
